Total Housing Cost

Base rent is not the full picture. Renter's insurance, utilities, parking, and pet fees add to monthly housing cost. Include insurance in this calculator for a realistic ceiling.

Roommates and Split Rent

If you share a lease, divide the affordable total by your share of bedrooms or income. Ensure all roommates meet landlord income requirements collectively.

Saving While Renting

Renters can still build wealth through retirement accounts and other investments. Use the Rent vs. Buy Calculator to see whether ownership or renting fits your timeline and market.
